THE CKANE-FLIES OF NEW YORK PART II 891 



Fully colored pupae dark brown; cephalic crest paler; pronotal breathing horns pale yellow, 

 darkening into brown at tips; wing pads light yellow, with dark venation showing clearly; 

 pleurites of abdomen of a darker brown than sternites or tergites. 



Body somewhat similar to that of E. longicornis, but general form much stouter. Cephalic 

 crest (Plate LVI, 287) prominent, tuberculate, consisting of four lobes, the posterior lobes 

 somewhat the larger, on posterior and lateral faces with two stout setae; a stout seta on 

 ventral face of anterior lobes. Scapal spine lacking. Clypeal tubercles large, blunt, with 

 a small setiferous tubercle above each. Labrum bluntly rounded at apex. Labial lobes 

 elongate, diamond-shaped, tips rather acute. Pronotal breathing horns rather long and 

 slender, transversely wrinkled, longer than cephalic crest. Mesonotum (Plate LV, 279) 

 more convex than in E. longicornis. Wing pads usually showing venation clearly on pale 

 background; vein r connecting Ri with Rz+s distinctive of this species, lack of cell Mi 

 separating this pupa from that of E. spinosa and E. brachycera. Legs sheaths ending about 

 on a level, the hind tarsi a little longer than the two inner pairs. 



Arrangement of setae on abdomen (Plate LVI, 288) about as in E. longicornis. Pleura 

 with two stout setae dorsad and caudad of each spiracle, and a weak seta ventrad of spiracle 

 and close to it; basal ring with a single pleural seta; spicules on caudal margin of posterior 

 ring small and numerous, on intermediate segments about forty in number; seventh sternite 

 with about four to six spines at each end of row, the broad median area devoid of spines. 

 Female cauda (Plate LV, 276) with tergal valves exceeding the long sternal valves, 

 scarcely directed dorsad (this condition may be compared with that in E. longicornis). Male 

 caada with abdomen bluntly rounded at tip.

Genus Penthoptera Schiner (Gr. sorrow + wing) 



1.X3 Penthoptera Schin. Wien. Ent. Monatschr., vol. 7, p. 220. 



Larva. Spiracular disk surrounded by four blunt lobes, the ventral pair a little the longer, 

 inner fac3 not marked with darker, at tip with one or more long setae. Head capsule about 

 as in Eriocera. Coloration a deep saturated yellow. 



Pupa.- Cephalic crest with lobes rounded, setiferous. No distinct tubercles or spines 

 on head or thorax. Pronotal breathing horns short, stout, cylindrical, apex expanded into 

 a flattened head, stem caarsely wrinkled, base enlarged. Abdominal armature weak. 

 Spiracles not well developed.

Penthoptera is a small genus which includes four European and three 

 American species, two of the latter occurring in tropical America. The 

 eastern North American Penthoptera albitarsis, discussed below, has been 

 considered in some detail by the author in another paper (Alexander, 

 1915c: 152-157).
